解答

展开

16 (x - 1)^{2} + 16 (- \frac{1}{4} x + \frac{1}{4})^{2}

17 x^{2} - 34 x + 17

求解步骤

16 (x - 1)^{2} + 16 (- \frac{1}{4} x + \frac{1}{4})^{2}

展开

16 (x - 1)^{2} : 16 x^{2} - 32 x + 16

= 16 x^{2} - 32 x + 16 + 16 (- \frac{1}{4} x + \frac{1}{4})^{2}

展开

16 (- \frac{1}{4} x + \frac{1}{4})^{2} : 16 \cdot \frac{x ^{2} + 1 - 2 x}{16}

= 16 x^{2} - 32 x + 16 + 16 \cdot \frac{x ^{2} + 1 - 2 x}{16}

化简

16 x^{2} - 32 x + 16 + 16 \cdot \frac{x ^{2} + 1 - 2 x}{16} : 17 x^{2} - 34 x + 17

= 17 x^{2} - 34 x + 17
